Displaying and maintaining MPLS L3VPN

You can soft-reset or reset BGP sessions to apply new BGP configurations. A soft reset operation updates BGP routing information without tearing down BGP connections. A reset operation updates BGP routing information by tearing down, and then re-establishing BGP connections. Soft reset requires that BGP peers have route refresh capability.

Execute the following commands in user view to soft reset or reset BGP connections:

Task

Command

Manually soft reset BGP sessions for VPNv4 address family.

refresh bgp [ instance instance-name ] { ipv4-address [ mask-length ] | all | external | group group-name | internal } { export | import } vpnv4 [ vpn-instance vpn-instance-name ]

Reset BGP sessions for VPNv4 address family.

reset bgp [ instance instance-name ] { as-number | ipv4-address [ mask-length ] | all | external | internal | group group-name } vpnv4 [ vpn-instance vpn-instance-name ]

For more information about the refresh bgp vpnv4 and reset bgp vpnv4 commands, see Layer 3IP Routing Command Reference.
